Orbit and dynamics
Between its closest point (0.845 AU) and its farthest (1.985 AU), the heliocentric distance changes by 1.14 AU over every revolution.
One full revolution takes 1.68 yr (615 days), computed from the semi-major axis of 1.415 AU.
The high eccentricity (0.403) produces a strongly elongated orbit, so the object spends most of its time far from the Sun.
The orbital plane is tilted 15.34° relative to the ecliptic.
By the vis-viva equation its orbital speed rises to 38.4 km/s at perihelion and falls to 16.3 km/s at aphelion.
Because q < 1 AU and Q > 1 AU, this orbit geometrically intersects the region of Earth's orbit.
Size and surface
No direct size measurement is available; from an absolute magnitude of H = 22.64 and an assumed geometric albedo of 0.14, the diameter works out to roughly 0.11 km.
Observation record and orbit quality
Astrometry from 182 individual observations underpins this orbit; the fit leaves an RMS residual of 0.3514 arcseconds.
Condition code U = 6 indicates a moderately constrained orbit; predictions decades ahead still carry noticeable uncertainty.
About these computed values
Orbital periods, perihelion and aphelion speeds, and diameter estimates on this page are computed by SpaceAtlas from the JPL SBDB orbital elements. They are derived quantities, not values copied from the source catalogue.
